The Air Department is the Navy’s finest and our largest department. More than 600 trained and highly motivated Officers, Chief Petty Officers and Sailors are charged with the primary mission of this great ship-to safely launch and recover aircraft. This involves operating and maintaining the ship’s catapults, arresting gear and visual landing aid systems. The department also ensures the safe movement and security of assigned aircraft in the ship’s hangar bay and on the flight deck.

The Engineering Department provides technical expertise for the safe operation and maintenance of the ship’s machinery systems. The department is manned by Sailors from Auxiliary, Damage Control, Electrical, Maintenance and Repair Divisions. They are the masters of all engineering disciplines. From the anchor at the bow, to the steering gear in the stern, engineers have responsibilities within every space on board. Engineers lead from the front and are the workhorses behind the equipment that sustains superior combat operations at sea.
